Boiler Corrosion | Major Causes of Corrosion

Boiler Corrosion is slow poison for Industrial Boilers. Corrosion is a phenomenon in which atmospheric oxygen in the air or water reacts with the metal to form oxides. Corrosion in industrial boilers is a phenomenon in which the oxygen that is dissolved in the water inside the boiler reacts with the metal of the steam boilers.

Explosion in Pulverized Coal Fired Boiler due to Waterwall

Waterwall tube failures are not uncommon in coal fired boilers. The failures reasons can be many starting from short term overheating to long term overheating, corrosion, erosion, etc. Waterwall tube failure in the burner panel corner in a tangential fired boiler and waterwall tube failure in the burner opening of a front wall fired boiler can lead to minor to sever explosion in the boiler.
